The technical scheme includes that the novel clutch master cylinder assembly for the automobile hydraulic clutch system comprises a cylinder body and a piston capable of moving inside the cylinder body; a first oil cavity is arranged inside the cylinder body; the first oil cavity is communicated with an oil outlet on the cylinder body; an oil inlet pipeline is arranged on the cylinder body; and the master piston leather cup is arranged at the end portion of the piston. The novel clutch master cylinder assembly is characterized in that a second oil cavity is arranged between the outer side of the front portion of the piston and the inner side of the cylinder body; the second oil cavity and the first oil cavity are connected through a tapered hole; the master piston leather cup positioned on the inner side of the tapered hole matches with the tapered hole; and the second oil cavity and the first oil cavity can be communicated or separated through movement of the master piston leather cup; and a compensating hole of the oil inlet pipeline is communicated with the second oil cavity.
Description
Technical field
The utility model relates to a kind of automobile hydraulic clutch system with novel Clutch main cylinder assembly.
Background technique
The Clutch main cylinder assembly of automobile hydraulic clutch system uses very frequent in automobile running, and is therefore, also very high to the requirement in piston primary cup working life of Clutch main cylinder.As shown in Figure 1, existing Clutch main cylinder assembly mostly is the compensation cellular type, in view of present manufacturing process, inevitably there is the aperture wedge angle on the compensate opening 1, along with moving back and forth of piston, as shown in Figure 2, when building pressure condition, piston primary cup 2 front ends are frequent being squeezed in the compensate opening 1 under the effect of high pressure, and the aperture wedge angle will increase the weight of the wearing and tearing of piston primary cup, has a strong impact on the working life of piston primary cup.
The model utility content
Goal of the invention of the present utility model is to provide a kind of automobile hydraulic clutch system with novel Clutch main cylinder assembly, can effectively prolong the working life of piston primary cup.
Realize the technological scheme of the present utility model purpose:
A kind of automobile hydraulic clutch system comprises cylinder body with novel Clutch main cylinder assembly, is provided with first oil pocket in the cylinder body, and oil pocket is connected with oil outlet on the cylinder body, and cylinder body is provided with inflow pipeline; Also comprise the piston that can in cylinder body, move, pistons end is provided with the piston primary cup, it is characterized in that: between the outside, piston front portion and cylinder body inboard, be provided with second oil pocket, link to each other by cone shape hole between second oil pocket and first oil pocket, the piston primary cup is positioned at the inboard of cone shape hole and matches with cone shape hole, can make between second oil pocket and first oil pocket by moving of piston primary cup to be communicated with or to cut off; The compensate opening of inflow pipeline is connected with second oil pocket.
The compensate opening of inflow pipeline is positioned at the top at piston primary cup rear portion.
Compensate opening is positioned at the tail end of inflow pipeline.
The second oil pocket diameter is greater than first oil pocket.
The beneficial effect that the utlity model has:
The utility model is adjusted the compensate opening position, can effectively avoid of the infringement of compensate opening aperture wedge angle to the piston primary cup, can effectively prolong the working life of piston primary cup, master cylinder, simultaneously, the utility model also has advantage simple in structure, easy to process, that cost is low.

Fig. 1 is existing compensation cellular type Clutch main cylinder structural representation;
The partial enlarged drawing of piston primary cup part when Fig. 2 builds pressure condition for existing Clutch main cylinder;
Fig. 3 is a structural representation of the present utility model;
The partial enlarged drawing of piston primary cup part when Fig. 4 is the utility model Clutch main cylinder free state;
The partial enlarged drawing of piston primary cup part when Fig. 5 builds pressure condition for the utility model Clutch main cylinder.
Embodiment
As shown in Figure 3, be provided with first oil pocket 6 in the cylinder body 7, oil pocket is connected with oil outlet 9 on the cylinder body, and cylinder body is provided with inflow pipeline 5; Also comprise the piston 11 that can move in cylinder body, pistons end is provided with piston primary cup 3.
As shown in Figure 3, Figure 4, be provided with second oil pocket, 8, the second oil pocket diameters greater than first oil pocket between the piston front portion outside and cylinder body 7 inboards, link to each other by cone shape hole between second oil pocket 8 and first oil pocket 6, piston primary cup 3 is positioned at the inboard of cone shape hole.As Fig. 4, shown in Figure 5, the compensate opening 4 of inflow pipeline is connected with second oil pocket 8.The compensate opening 4 of inflow pipeline is positioned at the top at piston primary cup rear portion, and compensate opening 4 is positioned at the tail end of inflow pipeline 5.
As shown in Figure 4, during Clutch main cylinder place free state, there is the gap in piston primary cup 3 with cone shape hole, and win oil pocket 6 and second oil pocket 8 are communicated, and two oil pocket hydraulic pressure equate.Promote piston push rod 10, piston primary cup 3 is along with piston is moved to the left, piston primary cup and cone shape hole gap diminish gradually, when the position that moves to as shown in Figure 5, piston primary cup 3 forms interference fit with cone shape hole, the first oil pocket internal diameter, and first oil pocket and second oil pocket cut off, master cylinder first oil pocket 6 begins to build pressure, pressure is along with being moved to the left gradually of piston primary cup strengthened, and is delivered to clutch by the pipeline that is connected oil outlet 9, makes clutch separation.
After the power that removes on the piston push rod 10, because the pressure of first oil pocket 6 is greater than the pressure in second chamber 8, the pressure difference in two chambeies impels piston 11 along with the piston primary cup moves right, and moves down into position shown in Figure 4 at clutch pedal return spring and action of inertia, and Clutch main cylinder is got back to free state.
Claims (4)
